AbstractFilter factors that determine an upper limit for the wave numbers for which refractometer measurements can be used to calculate the spectrum of refractivity are derived in this paper based on the assumption that refractometers measure a weighted average of the refractive index in a volume of air surrounding the center of the refractometer cavity. Two models are used assuming the weighting function has spherical symmetry around the center and one model is used assuming the function has cylindrical symmetry. All models result in a simple mathematical form which should be easy to use in further theoretical developments.
